Comparison of Microspectrophotometry and Room-Temperature Fluorescence Excitation-Emission Matrix Spectroscopy for Non-Destructive Forensic Fiber Examination

This project will examine the contribution of intrinsic fluorescence impurities (i.e. impurities imbedded into the fibers during fabrication of garments) - as a reproducible source of fiber comparison. This project will investigate spectral changes that might occur in textile fibers as a result of exposure to environmental conditions such as laundering, exposure to cigarette smoke and weathering. Understanding these effects will improve the understanding of textile physical, chemical and spectral changes that might affect fiber comparison via MSP and/or fluorescence microscopy. ca/ncf
